Collective intelligence in test and SCRUM teams
summary
Claims that a measurable c‑factor predicts group problem solving better than the smartest member or average IQ and that three practical predictors matter: equal speaking turns, average social sensitivity measured with the Reading the Mind in the Eyes test, and diversity split into cognitive and demographic components. Evidence includes the crowd beating experts 91% vs 65% and a working case: the Nokia Moller python library built by a cross‑functional team. Remedies are structured facilitation, social‑sensitivity training, hallway testing and deliberate cognitive diversity when hiring.
